Abstract: To remove flux residues from a bow-type electrode which can be heated by electrical resistance heating, the bow-type electrode is heated to a temperature (for example 750 DEG C) which is above the maximum soldering temperature and at which the flux residues decompose thermally. The decomposition products then drop off spontaneously or they can at least readily be brushed off. Cleaning by thermal decomposition of the flux residues can be carried out in a few seconds.

Abstract: A cassette (14) for producing coffee by the cup or pot and for use with a liquid receptacle (12) having an internal locking flange (26). The cassette comprises a ring (36) defining an interior and forming a bottom annular groove (32) to receive the locking flange (26) of the liquid receptacle (12) and thereby to hold the cassette in place therein. The cassette further includes a plurality of ribs (40) connected to and extending across the ring and separating the interior thereof into a multitude of sections, and coffee particles (24) disposed in said sections. A bottom filter (44) and a top filter (42) are secured to the ring and extend across the bottom and top, respectively, of the interior of the ring to hold the flavoring particles therein. Preferably, the cassette is packaged in a sealed vacuum pack; and as it is so packaged, the mass of particles in each section of the cassette is reshaped slightly and formed into a firm conglomerate, which facilitates the subsequent flow of hot water through the cassette.

Abstract: An inspection apparatus for the internal inspection of tubular members has a body 1 adapted for insertion into the tubular member and the body has an inspection window 2. A projection means including a laser 14 and associated reflectives 13, 10 and 9, the reflective 9 being rotated by a motor 7, is directed such that a beam of radiant energy is directed through the window to illuminate an axial extending strip of the entire 360° interior circumference of the tubular member. Light reflected from the tubular member passes through the window 2 and is reflected by reflective 8 onto a camera 12 which, via transmitting circuitry 16 transmits the image ring C and the light reflected by the window B back to a monitor 51 at the well head and to a computer 52 where the data transmitted from the camera is correlated with predetermined data values to determine damage to the interior surface of the tubular member such as ovality or corrosion. 
     Where the inspection apparatus is to be inserted into a tubular member containing liquid, in a feature of the invention, a device is provided for cleaning the inspection window and for maintaining the inspection window free from liquid. Such a device includes a reciprocal axially movable cam/wiper ring 29 having an interior surface provided with means for cleaning the window and an outer surface which is adapted to engage with a plurality of spring fingers 18 which support a membrane 19. When, in operation, the spring fingers are raised by the ring 29 the ring cleans the window and in moving axially upwardly moves the spring fingers 18 radially outwardly to engage with the interior surface of the tubular member to be inspected. At substantially the same time as the spring fingers are raised, an inert gas is directed below the membrane so as to form a gas bubble that covers the window 2 so that the radiant energy has a clear passage from the window the interior surface of the tubular member to be inspected.

Abstract: In the speaker system, an acoustic pipe for conducting a sound wave is arranged in front of a speaker for reproducing a middle and low frequency sound. The acoustic pipe has a rectangular open end portion. A speaker for reproducing a high frequency sound is disposed within the acoustic pipe coaxially with and in front of the speaker for reproducing the middle and low frequency. With this construction, attenuation of middle and high frequency components of sound signals which are produced from the middle and low frequency sound reproducing speaker is suppressed. Moreover, it is possible to conduct the high and middle frequency components and a high frequency component, which is reproduced by the high frequency sound reproducing speaker, as naturally composed sound signals to the open end portion of the acoustic pipe. The speaker system thus exhibits excellent characteristics in sound image localization and articulation of sound, thereby providing a high tone quality to the TV. The TV may be miniaturized with the speaker system.

Abstract: Das Verfahren dient der Herstellung eines kohlenstoffhaltigen Sinterkörpers aus Stahlpulver. Bei diesem Verfahren wird das Stahlpulver in einer zumindest zeitweise Kohlenmonoxid enthaltenden Atmosphäre auf Sintertemperatur erwärmt, über einen vorbestimmten Zeitraum auf Sintertemperatur gehalten und der hierbei gebildete Sinterkörper nachfolgend abgekühlt. Bei diesem Verfahren soll der Kohlenstoffgehalt des herzustellenden Sinterkörpers in einfacher und in für eine Serienfertigung geeigneter Weise auf einen vorgegebenen Wert eingestellt werden. Dies wird dadurch erreicht, dass der Partialdruck des in der Atmosphäre befindlichen Kohlenmonoxids während der Ausführung des Herstellverfahrens gezielt verändert wird, und dass diese Änderung derart gesteuert wird, dass der Kohlenstoffgehalt des Sinterkörpers nach Ausführung des Herstellverfahrens auf den vorbestimmten Wert eingestellt ist.

Abstract: A scanning device is described which comprises an optical head for scanning tracks (2) in an information plane (1) by means of three beams. Each beam is detected by a separate detection system (10, 11, 12). A new reference signal S r  is derived from the detector signals by a special electronic circuit (22, 24, 25, 26). Control signals for the beams, derived from the detector signals, can be normalized with this signal in such a way that the intensity of the beams no longer influences the value of the control signals. The Figure shows the formation of the reference signal and the normalization of the tracking error signal E t  by means of a divider circuit (27). The reference signal can also be used to detect reflectance errors in the information plane.
